The literal definition for ass-cheese is the sweaty, smelly grime that can be found between the butt cheeks of an unwashed crack, more often found at the very beginnings of the cavity just below the rump.

Other definitions include the use of the word describing things and/or situations equally foul or smelly.

Ass-cheese can be used in replacement of similar words that describe things and conditions that are unfavorable.
'MAN!! This bathroom smells like ass-cheese!!'

When you shart in your pants and your in such a situation that you can't immedietly get somewhere to change your underwear or you don't realize there is actual poop fermenting inside your pants so you don't think to change your undergarments or you don't care enough to change your underwear. The stinky fart solution saturates your underwear and begins the aging process much like aged cheese.
